723361 ÷ 80 
We're looking to find how many times 80 goes into 723361.

Step 1:
The number 80 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 80

Let's proceed to step 2:
The number 80 fits into 72 0 times, leaving a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 80

On to step 3:
80 can be fit into 723 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 720 from 723 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 80

Advancing to step 4:
If we divide 33 by 80, we get 0 and a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtract 0 from 33 to get 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 80

Moving on to step 5:
80 can be fit into 336 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 904.0
The remainder is 16 after subtracting 320 from 336.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 80

Step 6:
The number 80 fits into 161 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 9042.0
Subtracting 160 from 161 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 80 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 9042.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
80 goes into 100 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 9042.01
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 9042.012
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9042.0125
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9042.0125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9042.0125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 9042.0125, with a leftover of 0.0.
